MODE OF SECURING THILLS TO AXLE$.

Specification of Letters Patent No. 14,417, dated March 11, 1856.

To all whom it may concern Be it known that I, MATTHIAS SOVEREL, of Orange, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Securing the Bolts that Connect the Thills to the Axletree of a WVagon; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, which drawings are lettered to correspond with and make a part of this specification.

Des0m'pti0n.Figure 1, letter (A,) represents an oblique end, and side vlew, of my improvedthill fastener, or safety bolt, attached to a block of wood. Letter (72,) is the catch, or lock, that prevents the bolt (f,) from moving endwise, unless the catch is unlocked, and forced up into the horizontal opening of the spring chamber (0) the bottom part of catch (6,) (which is inside of the spring chamber,) forms the nut into which the bolt (f,) is screwed; that is more fully illustrated at Fig. 2. Hence when the catch, and spring, are forced along the spring chamber (0,) the bolt is also carried with them sufficiently far to allow the thill (6,) to fall out of its place, or to be taken out if required. (61,) represents a bolt that passes through the axle tree, having a round eye sufiiciently large to allow the bolt (f) to pass through it into the spring chamber; (J is another bolt that passes through the axletree, having a square eye to receive the square end of the bolt (f) this arrangement prevents the bolt from coming unscrewed, by any movement of the shaft (6.)

Fig. 2, letter (D,) is the thill bolt. (E, E,) represents the catch, and nut, which prevents the bolt (D), from'moving endwise. (F,) is the spiral spring. (G, and H,) are sections of the eyes of the bolts (03,) and (J,) Fig. 1.

The great risk of losing the nuts of the bolts, which connect the thills of a wagon to the axletrees, and by which means our lives are often endangered, has been obviated by the above simple arrangement, the separate parts of which are not new, but the mode of combining the spiral spring and the nut (or catch) for the purpose of operating the bolts, at the same time, keeping it fixed at either extreme if required, by means of the transverse slot at either end of the spring chamber, I believe to be new, novel, and useful.

Therefore what I claim as new, and novel, and desire to secure by Letters Patent, is

The combination of the spiral spring (F,) and the catch or nut (E, E,) and the eye of the bolt (H,) Fig. 2, and the spring chamber and slots (0,) Fig. 1, substantially as described in the above specification.

In testimony whereof I hereunto subscribe my name in the presence of two witnesses.

MATTHIAS SOVEREL.
